Title: Ladle using shape memory alloy
Inventor: KAWABATA HIROBUMI
IPC: A47J43/28
Filed: 1995-06-05
Abstract: PURPOSE: To provide a laddie not generating a gap when held between a pot and a pot lid by using a shape memory alloy in the handle part of the metal part of the ladle so as to prevent that the part coming into contact with the edge side of the pot is bent by temp. and the laddie slides into the soup of the pot. CONSTITUTION: A shape memory alloy is used in the part of the handle 1 of the metal part of a ladle and, at the time of use, the part 2 using the shape memory alloy is brought into contact with the edge side of a pot 4 to be put in the heated pot 4. Whereupon, the part 2 using the shape memory alloy is bent by the temp. of the edge side 3 of the pot 4 to hook with the edge side 3 of the pot. When a pot lid 5 is applied to the pot, a gap is eliminated between the edge side 3 of the pot and the pot lid 5 because the part 2 of the ladle is bent. When the ladle is released from the contact with the edge side 3 of the pot, the part 2 using the shape memory alloy is cooled to become straight.

Title: Controller for water heater
Inventor: EGAMI TOYOHIKO
IPC: F24H1/10
Filed: 1990-06-29
Abstract: PURPOSE:To reduce an overshoot or undershoot of supplied hot water temperature, by adding a compensatory element for advancing phase to at least one of feedforward input values, to feedforward calculating elements for a water heater. CONSTITUTION:Upon a change in water quantity from a steady-state condition, a feedforward calculating means 21 immediately calculates a combustion quantity G after the change, and outputs the calculated quantity G. A compensatory element 24 advances the phase of the inputted combustion quantity G by an amount corresponding to a delay due to a first delay element 22, and outputs a signal G'. For example, when the transfer function of the delay element 22 is a primary delay represented by l/(1+T1S), the delay in transfer at the element 22 can be completely compensated for by providing the compensatory element 24 with a transfer function represented by 1+T1S (assuming that T0 = T1). Therefore, the combustion quantity G inputted from the first delay element 22 to a second delay element 23 conforms to a transient condition of the second element 23 at that timing, so that variations in hot water temperature due to variations in water quantity can be suppressed. It is thereby possible to render an overshoot or setting time extremely small, even upon a change in set temperature or at the time of initial heating-up operation, and to ensure good hot water supply characteristics.

Abstract: PROBLEM TO BE SOLVED: To shorten and automize a casting preparing work by executing the shift of short side plates in a mold at the speed and the torque as low as possible and controlling a gap distance with a dummy bar head at the time of stopping the shifting. SOLUTION: Firstly, at the time of shifting the short side plates 1 in the mold, a mold 3 for changing the mold width is set at the low speed and the low torque and brought into contact with the dummy bar head 9 by using a screw shaft 2.
